My next door neighbor is replacing the asbestos roofing tiles on her 45 year old back house. The men doing the work are wearing gas masks. The dust and particles from the removal are flying over my six foot fence which sits about three feet from the structure. My two year old twin daughters were playing in the driveway adjacent to the work area. Is it safe and customary to remove asbestos tiles without some kind of tenting to prevent the dust from blowing into adjacent living areas? If we have been exposed to carcinogens what are the risks? Is it possible my children will contract asbestosis?

the answer no. 1 is correct. this is nothing to be trifled with
